Catalytic amounts of bromodimethyl sulfonium bromide, or Nafion-H along with NaI (1 equiv.), in methanol cleave a variety of TBDMS ethers readily in high yields. Alkyl TBDMS ethers react more readily and selectively compared to phenolic TBDMS ethers, benzyl, and methyl ethers.
摘要 溴化二甲基溴化锍或 Nafion-H 以及 NaI(1 当量)在甲醇中的催化量可轻松以高产率裂解各种 TBDMS 醚。与酚类 TBDMS 醚、苄基和甲基醚相比,烷基 TBDMS 醚更容易和选择性地反应。
